What are car insurance groups?

When calculating the cost of premiums, car insurance providers use a Group Rating system to determine the safety and security risks of all makes and models of cars, as well as repair costs and times. In other words, the likelihood of the car owner having to make a claim.  
Every private registered car in the UK is put into a car insurance group ranging from 1-50. Cars in the same group will typically have similar characteristics. The higher the group, the more expensive your premium is likely to be.  
The Group Rating system is administered by industry advisors Thatcham Research on behalf of the Association of British Insurers (ABI). Thatcham provides ABI with information that is used by a Group Rating panel to decide which group a vehicle will be put into. 
Group ratings are intended to be used as recommendations. While most insurance providers use this system, some also use their own rating systems to calculate the cost of their premiums. 

How are car insurance groups decided?

The Group Rating panel, made up of members of ABI and Lloyds Market Association (LMA), decide which insurance group new cars fall into based on the following information provided by Thatcham Research:

  • Damage and parts costs – likely extent of damage to each model and the cost of parts to repair it. The lower these costs, the more likely the car will be put into a lower group.
  • Repair times – the longer a car takes to repair, the higher the repair costs will be. For example, a car with parts that are widely available and easy to source should be quicker to repair than a rare model with parts that may take longer to find. So, a common model is more likely to be put into a lower insurance group, and the rarer model a higher group.
  • New car values – the more expensive the car, the higher the group is likely to be. A new car’s value is a good indication of the potential cost of repairs and replacement cost if the vehicle is written off.
  • Parts prices – a standard list of 23 common parts is used to compare the costs of the same parts between different manufacturers. The lower the costs, the lower the group is likely to be.
  • Performance – acceleration and top speed are also used to determine a car’s insurance group. Statistically, high-performance cars mean more frequent insurance claims, so they tend to be put in higher groups.
  • Safety – cars fitted with Autonomous Emergency Braking (AEB) systems are less likely to be involved in low speed front-to-rear accidents, like ‘shunting’, so might end up in a lower group.
  • Bumper compatibility – the alignment and structure of the bumpers can also affect the severity of a shunting accident (driving into the back of another car), so, if your car’s bumpers meet the insurance provider’s criteria, it might be placed in a lower group.
  • Security features – standard security features fitted by the manufacturer will be assessed. Features like alarms and immobilisers, glass etching, coded entertainment systems, wheel locks and visible VIN numbers could help to lower your insurance group and premium cost.

What are the car insurance groups?

In 2009, the car insurance groups were increased from 1-20 to 1-50. This wider range is more accurate and factors in the increased ranges and features of new cars available on the market today. For this reason, different versions of the same model can be found in different groups. For example, different versions of the MINI Clubman can range from Group 12 right up to Group 40.

You can get an idea of the types of cars in each Group below:

Group 1

Cars in Group 1 include:

  • Citroen C1
  • Fiat Panda
  • SEAT Mii
  • Skoda Citigo
  • Volkswagen Up

Group 2

What insurance group are electric cars in?

While electric cars offer low running costs, no tax and a cleaner environment, insurance costs may be higher than you’d like. This is because currently, parts and repairs can be more expensive to source and fit. As a result, electric cars are often put into higher insurance groups than petrol or diesel cars of a similar class and size.

For example, the Nissan Leaf Hatchback can be found in Group 21, while the Peugeot e-2008 SUV is in Group 25.

How is car insurance calculated?

The car insurance group isn’t the only thing that insurance providers will use to calculate your premium. As well as the car you drive, they’ll also want information about you.

The price of your premium can be affected by:

  • Your age – the younger and less experienced you are, the more expensive your premium is likely to be. But if you drive safely without any claims, you should see the price begin to drop once you turn 25. Older drivers over the age of 70 may also find they pay more for their car insurance.
  • Your postcode – if you live in an area with a higher crime rate, your premium might be more expensive as there’s more risk of your car being stolen or vandalised.
  • Your driving history – if you’ve made a number of claims or you’ve been convicted of a driving offence expect to pay a lot more for your car insurance.
  • Your job title – if you do a lot of driving for work or carry expensive equipment or goods in your car, it could have an impact on the price of your premium. Some types of employment are also considered more risky for insurance purposes.

How can I get cheaper car insurance?

First off, choose a car in a lower car insurance group. Cars in groups 1-10 are generally the cheapest to insure.

The following might also help you cut the cost of your car insurance:

  • Drive safely – safe driving is the best way to avoid accidents and build up your no claims discount.
  • Use a black box – young drivers can often get a discount on their premium by taking out a telematics policy and demonstrating safe driving habits.
  • Park your car off the street – parking on a private driveway overnight means there’s less risk of your car being damaged or stolen, so your premium might cost less.
  • Increase your excess – agreeing to a higher voluntary excess could mean a cheaper premium. Just make sure you can afford to pay the excess if you have to claim.
  • Pay annually – some insurance providers offer a discount if you pay up front in one go. Paying annually also means you’ll avoid interest on monthly payments.
  • Shop around – shopping around and comparing quotes from a range of providers could help you find a cheaper deal. Find out how much you could save by comparing car insurance though us.

Frequently asked questions

Are Group 1 cars always the cheapest to insure?

Group 1 cars are generally cheaper to insure, but the final cost of your premium also depends on your own circumstances and driving history. Based on our own data taken from a number of people with different ages, driving histories and postcodes, one of the cheapest cars to insure is the Dacia Sandero, which falls into Group 7.

Why are the same cars in different Groups?

The Group rating system takes into account the different versions of the same model of car. It also factors in the different age ranges for the same model. For example, there are loads of versions of the VW Golf. So, a 2013 1.6 TDI S Golf hatch might be in Group 10, while a 2020 TDI GTD Golf hatch might be in Group 27.

Do the car insurance groups include vans?

No. Light vehicles up to 3500kg have their own insurance group rating system which is also administered by Thatcham Research on behalf of ABI. Van insurance groups range from 1-30. Deciding factors are pretty much the same as for cars, but also include the weight of the van – the heavier the vehicle, the higher the group will be.
